3 claims (oise- 1735 YThe invention relates to Arule gaugesand hasA for `an object the provision ofa` gauge runner of compact, durable; anduinexpensive construction .i whichjcan be readily applied to i ametal rule lof the` thin flexiblepoclet type, the gauge runner being releasably clamped onthe rule to` `form a `T-square therewith, and being provided with a l clip` by which theinstrument may be held in the" pocket of the user. 10-

`Another object of theinvention is to provide 'ajgauge runner which is `constructed largely of* `sheet metal and'which `has a three-point engagev i .ment'with the opposite edges of the rule to in sure u ,l accurate squaring `with respect toV the rule. A further object of theinvention is to providel a rule gauge in which the `gauge"runner is irictionally retained in adjusted position on the? rule by spring means and is capable of being releasably locked in such position by a threaded member cooperating with the spring means.

The invention further consists in the `several features hereinafter setforth and `more particularly dened by the annexedclaims.` In the accompanying'drawing, Fig. View of a rule gauge embodying the invention;

In the .drawing, the numeral 15 designates a thin flat flexible steel rule of the type used by mechanics and suitable for pocket use. A gauge runner designated generally by 16 is `carried on the rule and is provided With arsheet metal frame 1 isa-front 17 `which slidably engages the rule.` The frame l'l includes a :dat bar portion 18=` `which 'extends transverselyof the rule and projectsbeyondythe" opposite edges of lthe rule. The bar portion 18 is in engagement with one face 'ofthe rule and'` has` reversely bentyend portions `19, as yseen Yin mENTA OFFICE Fig. 4, engageabie with theotherfface of menue.

The frame 17` is preferablyformed hof hardened Y steel, and the opposite edges of the barportion 18 are ground in parallel relation. `spaced hooks 20 are `-`formed on the frame 17 for engagement `with one edge oi the rule, and upstanding spaced parallel flanges 21 are formedinteg'rally `onthe' frame at a region `between the spacedrhooks20i A rod 22 is slidably `mountedin- `aligned bores' 23 formed in the flanges `21 and extends trans-` versely of the rule withits axis between the spaced lhooks 20. One end of the rod22fis provided; with" i an onset hook 24 engageable with theedge portion of theA rule opposite `'the one engaged by the The otherendof thebhooked rodis threaded to receive thereon `aknurled thuinb-y"V nut-forming sleeve 25 which is engageablewith theadjacent 1'1ange'21 of the frameffor clamping the runner on the rule.`` The oppositeedges of"` thefiat' bar portion1`8 of thefrarne arel disposed in perpendicular relationvt'o the edges oi the i rule and are retained in such relation' by-thethree-f point bearing ofthe runner on the rule vat the?V hooks 20 and 24. The sleeve 25 has a counterbore 25' to receive therein a compressed coiled spring 26 which bears against the adjacent flange 21for `frictionally retaining the runner on the rule, so4 that it will remain in adjusted position. The4 spring also prevents the sleeve 25 from backing 01T too freely, thereby avoidingaccidentalloss of parts. l 1

A pivot pin 27 extends transversely through the anges 21 and is secured at its ends to ears 28formed on a clip member 29.` Acoiled spring 30 surrounds the pivot pin 27 and urges the clip member in a direction in `which a terminal jaw 31 of the clip member normally engages'the outer face of the frame `17. The device may thus be carried in the pocket ofthe user in the `manner of a fountain pen. The clip member also permits the device to be picked up easily from a flat surface. i The rule` gauge of the invention may be used in numerous ways, some of which are illustrated in Figs. I to 13 ofthe drawing. t i

In Fig. 7. the device is used asa depth gauge ona Work piece 32. having an `opening 33, the runner being either set at a predetermined point on therule, or being slid along 'the rule into engagement with the outer face of the apering or marking the location of openings 36 in a` tured Work piece in which the end of the rule abuts.

In Fig. 8, the device is used for accurately setting a pair of outside calipers 34. The runner is set at a predetermined distance from one end of the rule and the calipers are then brought into Contact with this end of the rule and the ground straight edge of the runner. The device may also be used for setting inside calipers.

In Fig.' 9, the'devce is used as a hook gauge engageable with a work piece 35.V In this case the runner is preferably set at some integral calibration on the rule.

Fig. l shows the device in use for either checkwork piece 37. In this case the runner is set at some predetermined point on the rule `and is brought into contact with the edge of a work piece in the manner of a T-square, thus insuring accurate scribing or checking. When used as a 'l1-square the straight edge of the runner at either face of the rule is available.

v Fig, 11 shows the device in use for setting or checking the position of the cutting-off tool 38- withrespect to a rotatably driven work piece 39.

Fig. 12, the device is shown in use as a T-square in conjunction with a centering instru- `ment for a circular work piece 41 to facilitate the scribing of a center line perpendicular to and bisecting aline connecting spaced projections orI recesses 42 on the work piece.

Fig. 13 shows the device in use as al distance gauge on a work piece 43 with the opposite edge vof the bar portion 18 forming a reference surface.

When the Vrule rests on a flat surface, such as thextop of afdesk or bench, it isvelevated only slightly therefrom` bythe thin runner hooks 20 and 24 and thethin reversely bent portions 19 of the cross bar 18. The device can therefore be readily used as a T-square on straight-edged sheets of paper or other thin material resting on the at'surface.

What I claim as new and desire to secure by Letters Patent is:

engagingone face of the rule and having, two

guidebooks extending out of the plane'of said flat portion and embracing an edge of the rule, said frame having a straight edge extending transversely of the rule, a pair of spaced ears projecting froml opposite side edges of the flat portion of the frame on the opposite side of the plane of said flat portion from said hooks, a rod slidably passing through said ears transversely of the rule and intermediate said hooks and having a hooked end embracing the opposite edge of the rule, and a screw threaded member engageable with said rod for drawing the hooked end thereof into clamping engagement with said rule.

2. A gauge runner for a flat rule, comprising a sheet metal frame having a body portion slidably engaging one face of the ruler and having two guide hooks to embrace one edge of the rule at longitudinally spaced points of the rule, said frame having a straight edge extending transversely of the rule, a pair of spaced apertured rod-guiding ears rigidly projecting from the body portion of the frame on the same side of the plane of said rule face as said body portion and being disposed between the opposite side edges of the rule, a rod slidably passing through said ears.

transversely of the rule at a region intermediate the rule edge bearing 'points of said'body portion and having a hooked endembracing the opposite extending transversely of saidframe: at the same side of the said rule face as said body portion and slidably guided in said projecting portion, said rod having a reversely hooked` endin which the opposite edgevof the rule slidably ts and said rod having a screw threaded part the axisfofwhich `is at the sameside of said rule face as said body portion, and-ila screw threaded member engageable with the screwA threaded part of said rod for drawing the hooked end thereof intoclamping engagement with therule.
